Generalized multidimensional scaling (GMDS) is an extension of metric multidimensional scaling, in which the target space is non-Euclidean. When the dissimilarities are distances on a surface and the target space is another surface, GMDS allows finding the minimum-distortion embedding of one surface into another. GMDS is an emerging research direction. Currently, main applications are recognition of deformable objects (e.g. for three-dimensional face recognition) and texture mapping. (Wikipedia).

Multidimensional Scaling - An EXTREMELY POWERFUL algorithm
Entry to #some2 Multidimensional scaling is also similar to PCA and has other names as well. I hope this video informs you of the basics. You can probably analyse a clean dataset using it now if you know some R or Python. Top 1000 Instagram Influencer dataset: https://www.kaggle.com/d

BM8.3. Mappings 3: Composition and Inverse Mappings
Basic Methods: We define composition of mappings and draw parallels to multiplication of real numbers. Items include associativity, identity, and commutativity. Consideration of multiplicative inverses leads to the definition of an inverse mapping, and we give conditions for its existenc

Reliability 3: Cronbach's alpha and internal reliability
In this video, I discuss Cronbach's alpha and internal reliability. I also demonstrate how to compute Cronbach's alpha in SPSS and make sense of SPSS output such as corrected-item-total correlation, squared multiple correlations, and Cronbach's alpha if item deleted.
